Is this authentic? Vintage Seamaster 300 166.024 Big Triangle Family Heirloom Find

It looks like an 166.024 but this is uncharted territory for me. The clock isn’t spinning but when I change the time it ticks for a second just to stop again. Thanks for any information about this piece (value, year, etc.)

You did very well stopping her from throwing that watch out, some better pictures would be nice but that does indeed look like an authentic Seamaster 300 Big Triangle. That is a very nice watch.

Some nice high quality straight-on shots of the dial would be good so it can be seen clearly, and a shot of the movement with the serial number visible, its on the outer edge of the movement currently hidden by the rotor.

It's definitely a Ref 166.024, just want to get a better look at the dial and hands and see if the serial number is in the right range.

Sounds good, maybe in the mean time tell her to put it some place safe and FAR from the bin! lol.

Everything is looking good to me, a photo of the inside of the case-back is also helpful.

As an aside, the movement is in need of a service with some repairs to the auto-winding mechanism. You can see that the rotor has been rubbing against the case-back.
